Grant Hutchison's Spreadsheet for DSC Object Alignment

This Excel spreadsheet allows rapid initial orientation of billboard
objects and 3DS models, so that the billboard image or model is set up aimed
precisely towards the
Sun, with the top of the original image pointing towards celestial north.

The input data required are the right ascension and declination of the
billboard object - these values can be entered in decimal degrees, or
degrees, minutes and seconds. Right ascension can also be entered as decimal
hours, or hours, minutes and seconds.

The spreadsheet then calculates the necessary Axis and Angle commands to
orientate your billboard correctly - just copy the two lines from the
spreadsheet and paste directly into your dsc file.

Note that pasting into WordPad causes the cell formatting codes to
be included, not just the Axis and Angle text. Pasting into Notepad
works as desired: only the words Axis, Angle and their numeric values
are included.

The spreadsheet works correctly both with Microsoft Excel and
when imported into Open Office.
